STQVE FOR BURNING SOLID FUEL AND PROCESS OF MAKING SAME.

Specification of Letterb Patent.

Patented J une 4, 1918.

Application filed November 17, 1916. Serial No. 181,865.

To all whom it may concern:

'Be it known that I, HENRY PRICE BALL, a citizen of the United States, residing in Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Stove for Burning Solid Fuel and Process-of Making Same, of which the following is a specification.

This invention relates to improvements in stoves or lamps, which burn a solid fuel composed of alcohol and an absorbent and has for its objects- 1st. To improve the appearance of the container when it is open.

2nd. To observe leaks in the container so.

that defective stoves may be discarded.

3rd. To automatically repair small and gllVlal leaks without appreciable loss of I el. V

4th. To produce printed matters, in relief or intaglio, on the top of the fuel to be ex posed to view when the cover is removed.

These and further objects will more-fully appear in the following specification and accompanying drawings, considered together or separately: In the drawings- Figure 1 is a section of a container, with the cover removed, showing it in the first stage of the process.

Fig. 2 is a similar view, but with the cover in its first position.

Fig. 3 is a similar view, with the cover in its final position.

Fig. 4 is a similar view, showing the next step in the process in which the container is reversed.

Fig. 5 is a similar view, of the completed stove but with the cover removed.

Fig. 6 is an enlarged section of a portion of the upper part of the stove showingit in I and reversed position and indicating the manner in which leaks are automatically repalred Fig. 7 is a'detail sectional view showing, a modification of the manner in which the air space may be formed.

In all of the several views like parts are designated by the same reference characters.

In carrying out my invention I provide a container 1. This container is made of sheet metal or other material which will suitably resist the action of heat. It is adapted to serve as a means for transporting and storing solid fuel and also as a stove for burning said fuel. The container 1s provlded with a suitable top 2, of any size. Associated with thistop is a cylindrical neck 3. In the embodiment chosen for illustration, this neck extends inward. That portion 4 of the container opposite the neck may be bulged inwardly. The bul e may, if desired, be dispensed with'an the bottom of the container made of any other shape. In Fi 7 it is shown as flat.

ssociated with the container is a cylindrical cover 5 having a peripheral flange 6 thereon. The cover is of such a size that it will make a close fit with the inside of the cylindrical neck 3. By means of this close fit 1t is held in place by friction and a liquid and vapor tight joint is produced between the side walls of the cover and the cylindrical neck. The peripheral flange serves as a convenient means for removing the cover by the introduction of a suitabletool under it. Preferably the cover is provided with an embossed design 7 in the form of words or' figures or the like. Preferably this embossed design is made by distorting the sheet metal forming the cover so that the design may be in relief on the upper side of the cover and in intaglio on the under side.

Associated with the container hereinbefore described is a suitable fuel. This fuel is preferably made of alcohol and an absorbent. Preferably this absorbent is in the form of a soap. A suitable soap is made of stearic acid and sodium hydroxid. As an example, I may embody alcohol, one hundred parts, stearic acid, and suflicient sodium hydroxid to neutralize all or nearly all of the stearic acid. The fuel is compounded in the presence of heat and when hot is in the form of a liquid. This liquid, indicated at 8 in Figs. 2 and 3, is introduced within the container so that its top line 9 is below the top of the container. The cover is then introduced within the cylindrical neck and pushed down from the position shown in Fig. 2 to that shown in Fig. 3, or lower or higher as desired. The air or vapors within the container will be compressed but there will be suflicient space for extent that the liquid will cover the bottom of the cover 5, the bottom of the top 2,

fuel will be in close the seam between the top and the sides of the container aiid the joint between the cover and the neck 3, as shown in Figs. 4 and 7'. The liquid fuel will then enter the now lower part of the'contamer .and rest upon the lower face of the cov r and also, upon the lower face of the top 2. The air or vapor space 11 will then be adjacent to the Preferably the bottom 4 of the container. I bulge in the bottom 4, when employed 1s sufficiently deep so that the liquid fuel will,- 'when the container is reversed, be in contact with some, preferably the central, part of it as shown in Fig. 4. The fuel is now allowed to harden by. cooling and during the cooling operation as the mass contracts the central i ortion will adhere to the bulge and the level of the edge of the mass will be lowered thus forming a more or less conical shape, approximately as shown in broken lines in Fig. 4, so that when the container holding the hardened and solidified fuel 12 is reversed, as shown in Fig. 5, there will be an air or vapor space '11 adjacent to the ed on the bulge. At the same time the solid and intimate contact with the lower side of When the cover is removed, for the purpose of exposing the fuel for burning, the em bossed design 13 will appear either in relief or intaglio, on the top of the solid fuel and.

may be observed through the cylindrical neck. a

As shown in Fig. 7 .a container having a flat 'bottom is employed. When the cover is placed in position the container is partly inverted, the liquid willseekthe lower level and the space 11 will be left at the highest point in the container. When the fuel solidifies and the container'is placed bottom down the fuel will be supported on the bottom of the container.

In the event that a leak occurs in one of thejoints, for example, between the neck and the cylindrical cover, or at the seambetween the top and the sides of the container, the pressure of the air or vapor contained in the space 11 shown in Fig. 4 will force the liquid fuelthrough such joint. This fuel will then be forced upon the support carrying the container and the operator or workman, who is filling the contalner, will-observe that a leakhas appeared and then can discard the container. In the event that the leak is very small,'.for example, through the faultyseam 14, shown in Fig. 6 thenthere will be a ve small escape of fuel. When the fuel hardens the alcohol will evaporatein the immediate vicinity of the joint, leavin the solid absorbent 15 adjacent-to such'joint. This solid abscrbent in the embodiment-chosen. for illustration,

. the container. bulge and the solidified fuel will besupportthe top 2 and cover 5. a

' the fuel and a being a soapformed of stearic acid-and sodium hydroxid, will act as an effective dam. to. prevent further escapeor evaporation of. the j liquid alcohol. The amount. which will have escaped-previous to the formation of this dam and the containerwill therefore be as in all practical respects as' the one wit a the lea ing the presence of leaks, or to automaticall will be very little I regard the feature whereby the upper. a parry the container is filled with solid fuel as ery, important. In addition to indicatrepair small leaks, as hereinbefore describe v v and the imprinting 'of designs or other mat-v ter on'the upper surface of the fuel through the agency of the cover,

as also hereinbefore described, the container with the cover re moved has a much more pleasing. appearance Elfin; one which does not have the completely his is 11, whi,ch permit the cover to be closed and at thesame timefill'the entire upper part of v Having thus described my invention what I now claim as new and desire-to secure by 'Letters Patent, is: I 1. As a,new article of manufacture, a container having an openend, a cover cooperating with the opening, a-solidified fuel filling the container there being-a space between the fuel and the bottom ofthe' container.
